OF YOUNGSTOWN, OHIO.

SHOCK 'AIBSORBER FOR BICYCLES.

Application filed August. 26, 1924. Serial No. 734,259.

To all whom it may concern:

Be it known that I, HAROLD SoARNnoomA, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in a Shock Absorber for Bicycles, of which the following is a specification.

This invention relates to improvements in shock absorbers for bicycles and has for its primary object to provide a means whereby the operator of the vehicle may ride with comfort while traveling over rough and uneven surfaces.

Another important object of the invention is to provide a shock absorber of the above mentioned character, which includes a means for eliminating the vibrations caused by the wheels of the bicycle encountering rough portions of the road and further preventing any injury to the frame of the bicycle when such obstacles are encountered.

A further object of the invention is to provide a shock absorber for bicycles of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes for which it is designed.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation of my improved invention showing the same in use, and

Figure 2 is a rear end elevation thereof.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a bicycle fork forming a part of the frame A of a bicycle and as the same is of the well known construction, a further detailed description thereof is not thought necessary. Pivotally supported intermediate its ends between the lower free ends of the arms of the bicycle fork 1 is the yoke designated generally by the numeral 2. The pivotal connection between the yoke and the fork is illustrated at 3 in the drawing. Mounted in the forward end of the yoke 2 and the forward end of the bicycle form 1 is the wheel 4. The yoke 2 is curved slight- 1y downwardly toward the rear end thereof in the manner also clearly illustrated in Figure 1. v

Extending rearwardly from the upper portion of the bicyclefork 1 and inclined downwardly are the arms 5 and 6 respec tively. The upper or forward ends of the arms are secured to the bicycle fork 1 by any suitablefastening means such as is shown at 7 and the rearends of the arms are disposed above the rear portion of the yoke 2. A rod or bar 8 extends between the rear ends of the arms 5 and 6 and the purpose thereof will hereinafter be more fully described. Bracing means'such as is shown. at 9 extends between the lower portion of the bicycle fork 1 and the arms 5 and 6 adjacent the rear ends thereof whereby the arms are supported in a rigid position on the bicycle fork. Associated with the yoke 2 andthe arms 5 and 6 are a'pair of coil springs '10 I and 11 respectively; The upper ends of the springs are connected to the rear ends of the arms 5 and 6 respectively while the lower ends of the spring are fastened to the opposed sides of the yoke 2 adjacent the rear end thereof in the manner clearly illustrated in the drawing.

For the purpose of limiting the'expansion of the coil springs 10 and 11 and the downward movement of the rear end of the yoke 2, the safety strap 12 is provided and the same extends around the rod 8 between the arms 5 and 6 and the rear portion of the yoke 2 in the manner as more clearly illustrated in Figure 2. The strap is provided with the usual buckle 13 whereby the same may be adjusted for increasing or diminishing the loop formed thereby as may be desired.

It is of course to be understood that each of the forks is provided with a shock absorber of the above mentioned character, and as the parts are of the same construction, the description of one is thought sufficient.

The provision of a shock absorber for bicycles of the above mentioned character will enable a person operating the same to ride comfortably over any rough or uneven surface which may be encountered and yet enable a person to properly control the propulsion of the bicycle. Furthermore the provision of a shock absorber of this character will prevent any possibility of the forks of the bicycle from buckling as frequently happens when the wheels of the bicycl fenonniei' rdligh plates in "tlfe ioad. The pa31ts-of the present inventien so arranged as to enable the same to be'i'e'z'idfly' assembled or disassembled? as me-y be new essary.

While I have shown the prefeered em bodiment of my invention, it is tobe understood that various ehangesinthe-size, shape andel rengement of parts may the resortedto witness departing frofiiftli' spirit of invention; and the scope of the appended claims.
